Update on part (b): I read somewhere (I think it was on www.maltwhiskey.com)
that the Cigar Malt is a vatting of whiskies from 10 to 20 years old, thus making it a "10yo". Whatever the case may be, there is definitely a good bit of older whisky in the bottle.
Part (c): In PA/USA, the Cigar malt is actually a few pennies cheaper than the 12yo, both selling for around $27-$28US. The Dalmore 21yo (one of my favorite whiskies) goes for around $65US.
